Pool Pump Running Dry?
If your pool pump sounds like it’s running dry, or water just isn’t circulating, there’s a good chance it’s lost prime. Priming your pool pump is a simple but important process that ensures water is flowing properly through your system. Without it, your pump can overheat, your pool won’t filter correctly, and you might be looking at an avoidable service call.
Below is a straightforward guide to get your pump back in action.
Step-by-Step: How to Prime Your Pool Pump
1. Turn Off the Power
Always start by shutting off the power at the breaker or timer. Safety first—never open a pump lid while it’s running.
2. Open the Pump Lid
Unscrew the lid of the pump basket. You may hear a release of pressure, which is normal.
3. Clean Out the Basket
Remove any debris that could be restricting flow, including leaves, bugs, or dirt.
4. Fill the Pump Housing with Water
Using a garden hose or bucket, fill the pump basket chamber with water until it’s full. This helps remove trapped air and allows the pump to catch prime.
5. Check and Lubricate the Lid O-Ring
Before replacing the lid, inspect the O-ring for cracks or wear. Apply a small amount of silicone-based lubricant to ensure a tight seal and prevent air leaks. Then, screw the lid back on snugly.
6. Turn the Power Back On
Watch through the lid: water should begin circulating within 30–60 seconds. It might take a moment, but you should see a steady stream of water.
Troubleshooting Tips
If the pump still isn’t catching prime:
- Check the pool water level. If it’s too low and exposing the skimmer, air may be getting sucked into the system.
- Inspect the pump lid O-ring. Even a small air leak here can prevent the pump from priming.
- Use a garden hose in the skimmer suction port. After filling the pump, you can place a running hose into the suction hole at the bottom of the skimmer. This can help force water through the pipes and push trapped air out.
- Listen for hissing or gurgling. This may point to a suction-side air leak that needs repair.
Still Not Working?
If your pump won’t prime after following these steps, it may be a deeper issue like a clog, damaged valve, or air leak. Let the pros handle it from here.
